NAME
lp - PostScript preprocessors
DESCRIPTION
These programs are part of the lp(1) suite. Each corresponds to a
process in the -pprocess option of lp and exists as an rc(1) script in
/sys/lib/lp/process that provides an interface to a PostScript conver‐
sion program in /$cputype/bin/aux. The list of processors follows; af‐
ter each description is a bracketed list of lp options to which the
processor responds:
dpost converts troff(1) output for device post to PostScript. This is
used for files troff'ed on our UNIX systems that do not handle
UTF characters. [DLcimnorxy]
dvipost
converts tex(1) output to PostScript. [Lcinor]
g3post converts CCITT Group 3 FAX data to PostScript. [DLm]
gifpost
converts GIF image data to PostScript. [DLm]
generic
is the default processor. It uses file(1) to determine the type
of input and executes the correct processor for a given (input,
printer) pair.
hpost adds a header page to the beginning of a PostScript printer job
so that it may be separated from other jobs in the output bin.
The header has the image of the job's owner from the directory
of faces (see face(6)). Page reversal is also done in this pro‐
cessor.
jpgpost
converts JPEG image data to PostScript. [DLm]
noproc passes files through untouched.
p9bitpost
converts a Plan 9 image to PostScript, such as /dev/screen for
the whole screen, /dev/window for that window's data, and
/dev/wsys/.../window for some other window's data. [DLm]
pdfpost
converts PDF data to PostScript.
post passes PostScript through, adding option patches for paper tray
information. This does not always work with PostScript gener‐
ated on other systems.
ppost converts UTF text to PostScript. [DLcfilmnorxy]
tr2post
converts troff(1) output for device utf (the default) to Post‐
Script. See /sys/lib/troff/font/devutf directory for troff font
width table descriptions. See also the /sys/lib/post‐
script/troff directory for mappings of troff UTF character space
to PostScript font space. [DLcimnorxy]

BUGS
The file command is not always smart enough to deal with certain file
types. There are PostScript conversion programs that do not have pro‐
cessors to drive them.
